Medical-grade beta-tricalcium phosphate (β-TCP) is widely used as a synthetic bone graft material in orthopedics, dentistry, spinal surgery, and related medical fields. Because its composition is close to the inorganic phase of bone, it is often selected for projects that need a balance of biocompatibility, degradability, and osteoconductive support.
After implantation, β-TCP gradually degrades through bodily-fluid interaction and cellular activity, releasing calcium and phosphate ions that can participate in the bone-regeneration environment. Rather than serving as a permanent implant, it is commonly used where the material is expected to provide an initial scaffold and then progressively give way to newly formed tissue.
Osteoblast adhesion, growth, and matrix secretion are important to this process. Porous β-TCP structures can offer a larger surface area for cell activity and tissue ingrowth, while the material's handling and moldability also make it practical for bone-defect filling and related regenerative applications.
